High-quality a-plane-orientation single-phase wurtzite Mg<sub>0.48</sub>Zn<sub>0.52</sub>O thin films are demonstrated by X-ray diffraction and absorption spectra. The MgZnO photoresistors exhibit a large dark/photoresistance ratio up to 1.7 × 10<sup>4</sup> with the light intensity of 0.61 mW/cm<sup>2</sup> at 260 nm. The spectral response shows a sharp response peak only in the solar-blind region with maximum responsivity of 1.5 × 10<sup>-3</sup> Ω<sup>-1</sup>· W<sup>-1</sup>.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>X-ray diffraction; magnesium compounds; molecular beam epitaxial growth; photoresistors; thin films; Mg<sub>0.48</sub>Zn<sub>0.52</sub>O; X-ray diffraction; absorption spectra; r-plane sapphire substrates; radio-frequency plasma-assisted molecular beam epitaxy; solar-blind photoresistors; thin film growth; Absorption; Buffer layers; Diffraction; Optical buffering; Substrates; X-ray diffraction; Zinc oxide; <formula formulatype=$ $a$-plane MgZnO; photoresistor; resistance; solar blind;
